Abstract: VEHICLE SEAT SUSPENSION HAVING  VALVE CONTROLLED AIR SPRING                  Abstract of the Disclosure An adjustable seat suspension system for a vehicle seat for a tractor, earth working equipment, or the like, and in which the seat is resiliently supported by a pressurizable air bag. The seat suspension system provides a manually settable lever by means of which the operator can infinitely vary the height adjustment of the seat for a normal operating position, depending on his size. The seat suspension adjusting mechanism includes a valve for regulating the flow of pressurized air to or from the air bag. The arrangement is such that for any vertical height position selected by the operator, the air controlling mechanism permits the seat to oscillate up and down through a given range of movement, say for example six and one-half inches. In addition to a normal operating oscillation range for any selected height adjustment, the seat suspension control system of the present invention includes a floating pivot point in the control linkage which can shift from its normal operating position to thereby in effect disconnect the control valve and protect it when the seat movement exceeds the limits of  the valve spool,  which limits are small compared to overall linkage move-ment requirements.

Abstract: ENERGY TRANSFER CIRCUIT            Abstract An electrical load is energized from an energy source that may not have the capacity to carry the load directly.          More specifically, a capacitor is charged at a low charge cur-rent for a relatively long period of time and when the load is to be energized, the capacitor is discharged through the load in a relatively short period of time.  Current limiting devices protect the power source.  The charge and discharge intervals are initiated in response to polarity reversals of the power source.  When the power source presents one polarity, the ca-pacitor is charged; and in response to a polarity reversal, the capacitor is discharged through the load.  A plurality of capac-itors and associated load circuits may be connected to a single power source without feedback between the circuits.  A current limiting device may be used to limit the initial load current.  Typically, the load may comprise a plurality of lamps, horns, bells or buzzers to indicate an alarm condition.  Since the power supply is not required to directly energize the alarm devices, the power supply may be smaller and more economical.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention is a reinforced plastic article and a process of manufacturing the same. The article comprises at least one layer of a combination of glass fibres and steel cord.  The process comprises advancing a set of resin impreg-nated glass fibre rovings and a set of steel cords to a guiding system which is mounted in the vicinity of a mandrel and movable axially along the mandrel.  The fibres and cords are brought into mutual longitudinal contact by the guiding system and the parallel fibres and cords are guided as a layer onto the mandrel surface so as to arrange and embed each cord in a fibre roving.  The resulting reinforced plastic articles have improved mechanical properties such as strength, rigidity, impact resistance, etc.

Abstract: Method and Apparatus for Manufacturing Concrete Elements Abstract of the Disclosure A method and mould for manufacturing concrete elements by means of a turnable mould, whereby the concrete is cast in a main mould when the latter is in horizontal position while the mould is at the same time vibrated.  The mould has a closed construction and is used in such a way that, at the casting stage, the second half of the mould construction, which is hinged in relation to the main mould, is in vertical position.  Thereafter the mould construction is closed which causes a pressure on the concrete, whereby any excess concrete is extruded through the slit between the mould halves,  Then the entire mould construction is turned into vertical position while continuing the vibration so as to eliminate any air that has moved to the outer surfaces of the element.  The mould construction is turned further by 90° so that said second half of the mould, which comprises a frame and an auxiliary mould fastened inside the frame, remains underneath.  Finally the main mould is lifted into vertical position and the auxiliary mould is detached from the frame so as to shift the element away.

Abstract: Abstract Detection of exhaustion of sodium form water softeners is accomplished by subjecting sample of the outflow from a water softener to reverse osmosis in order to separate monovalent (so-dium) and divalent (hardness or magnesium and calcium) ions dif-ferentially from the outflow and measuring conductivity before and after the reverse osmosis.  The two conductivities are com-pared in a ratiometer or differential device.  After the softener becomes exhausted the divalent ion concentration in the outflow increases.  Consequently the conductivity ratio changes to indi-cate that the water softener has become exhausted.

Abstract: ABSTRACT OF THE DISCLOSURE             In the continuous production of iron by electrolysis of a ferrous electrolyte, the spent electrolyte is cooled before returning to a holding or regeneration tank, which tank  contains metallic iron for regenerating ferrous ions from the ferric ions.  The reconstituted electrolyte is heated before returning to the electrode-position cell.  By reducing the temperature of the spent electrolyte the rate of hydrolysis of ferric ions to form oxides of iron, called sludge, is reduced, thus increasing the interval between periodic cleaning of the electrolyte regeneration system and the electrodeposition cell.  In preferred forms of the invention heat energy is transferred from the spent electro-lyte to the reconstituted electrolyte by means of at least one counter flow heat exchanger in the form of a hollow cylinder containing a plurality of tubes made of titanium.  There may be a controllable cooling device disposed between the holding tank and the or the last heat exchanger for maintaining the temperature of electrolyte in the holding tank at a selected value.

The instrument features an improved solder tip consisting of a copper core clad with iron in the form of a cap. This permits working of the composite structure, for example, by crimping it, by pressing it to obtain a wedge-shaped tip, or by hammering it to elongate it to provide a desired shape.  The copper core may be made with a bore to provide an air duct for supplying hot air or for drawing away solder for desoldering operations.  The instrument also provides an improved sheath for the heater cartridge and heater to facilitate removal of the solder tip.  In addition, the heater element may be provided with one or more sensors, for controlling its temperature and for providing a temperature display.        The temperature display may include a sensitivity control to accommodate the instrument to different solder tips and to convert the instrument to a temperature probe.
